Active ski bindings can reduce lower extremity injuries by calculating tibia torsion. This study introduces a new biomechanical model accounting for inertial and velocity-dependent torques, improving injury protection.

Area of Science:

  • Biomechanics
  • Sports Engineering
  • Injury Prevention

Background:

  • Snow ski bindings aim to prevent lower extremity injuries.
  • Current systems inadequately measure tibia torsion, relying solely on leg displacement.
  • A need exists for advanced models to accurately assess torsional loading on the tibia.

Purpose of the Study:

  • To define a biomechanical model for calculating tibia torsion from boot-ski interface loading.
  • To investigate the contributions of inertial and velocity-dependent torques to tibia loading.
  • To present a novel analog controller for active ski binding systems.

Main Methods:

  • Developed a biomechanical model to calculate tibia torsion.
  • Measured torsion loading at the boot-ski interface.

Related Experiment Videos

  • Analyzed displacement-dependent, inertial, and velocity-dependent torques.

    • Main Results:

    • Tibia torsion calculation requires inclusion of inertial and velocity-dependent torques, not just displacement.
    • A new analog controller incorporating inertia, damping, and stiffness terms was designed.
    • The model provides a more comprehensive assessment of tibia loading.

    Conclusions:

    • Accurate tibia torsion calculation is crucial for active ski binding control.
    • The proposed biomechanical model and controller enhance the potential for preventing ski-related injuries.
    • Future active control systems should integrate these advanced loading calculations.
